Hello dear,
Chances of getting infected with
hiv/253657?iL=true" >AIDS are minimal with pin prick
injury as transmission requires blood to come in contact.
Even if there is contact with blood, dry blood is not infective.
However if it was a rusted pin, chances of tetanus is there, so I advise you not to worry and get a
tetanus toxoid injection.
To relieve your concern regarding HIV infection, you can undergo certain tests like p24 assay or PCR for HIV, which becomes positive within a week and are almost 100 % sensitive.
Even the presence of a single virus in the body can be detected by PCR.
So, if this test comes negative, you can be sure that you are safe.
Wishing you a good health.
Take care.
